Study Notes
Life Cycle of Parasitic Worms
- Unembryonated eggs are excreted in feces.
- Only embryonated eggs are capable of causing infection, requiring a maturation period of 15 to 30 days.
- Transmission occurs through the ingestion of embryonated eggs, commonly due to food contamination.
- Upon entering the small intestine, eggs hatch and release larvae.
- Larvae mature into adult worms, which colonize the cecum and ascending colon.
- Adult worms reside primarily in the cecum and ascending colon.
- Female adult worms begin oviposition approximately 60 to 70 days post-infection.
- Each female can lay between 3,000 and 20,000 eggs daily.
- The average lifespan of adult worms is around one year.
